I played COD4 on my first PC, and it played pretty well, with the graphics on high resolution, and playing with hardly any slowdown and skipping. Then I got rid of it, and bought this new one, installed COD4, and there's slowdown everywhere. It's bloody annoying, and I'm not even sure why it's doing it (I went down to 640x480 and turned off anti-aliasing before it bothered playing reasonably). Any ideas? When starting in the warehouse, it was lagging there when teaching you how to aim and hit targets, but I tried playing Counter Strike Source, and no slowdown when playing on the cs_office map..

I'm thinking of selling the card, and buying a better one - Any suggestions? I specifically want to play COD4 on a nice high resolution without slowdown. Some are recommending 8800GT or Radeon 3850 or something. Just want to see what you guys think? :)
